SECTIONAL RADIATOR TUBE, CONNECTOR, EXPAIilDER, AND-FLANGER.

Specification of Letters Patent.

Application filed November 18, 1912. Serial No. 732,031.

To all whom it may concern Be it known that I, JosnPrI Emma, acitizen ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a certain new and useful Improvement inSectional Radiator Tubes, Connectors, Expanders, and Flangcrs,

of which the following is 'a specification.

This invention relates to radiator connector expander-s and the like,and has for its object to provide a new andv improved device of thisdescription:

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a View of a radiator with parts broken away showing theconnection betweenv the sections when completed; Fig. 2 is a sectionalView showing the device in position ready'to complete the connection;Fig.

3 is a. sectional view similar to Fig. 2 show ing the parts after thedevice has been exand'ed; Fig. 4 1s asectronal view taken on 4 line ofFig. 3. Fig. 5 is a detail of the endpiece.

Like numerals refer to like parts through-- p out the several figures.

Referring now to the accompanying drawings, I. have shown a radiator 1made .up of a series of sections 2. These sections are connectedtcgetherby means of short tubes 3. The tubes are expanded and have their endsflanged so as to produce a tight joint. In F ig. 2, I. have shown anenlarged view in section with the tube and expand ing device in positiontherein ready to be operated. This expanding device consists of twosegment separate pieces 4 and 5, separate from each other and providedat the r ends with the enlarged or projecting portions 6 connected withthe body of the pieces 4 and 5 by means of the inclined faces 7. Thepieces 4 and 5 are hollowed out so as to provide the grooves 8. Anexpanding piece 8 is mounted upon a controlling rod or part 9 and isprovided with a beveled face 10 adapted to be forced between the pieces4and 5. The part 9 is preferably non-circular so that a wrench may beapplied thereto.

vSome means is provided for holding the ieces4 and 5 in position whilethe tool is being moved into the short tube 3. Any suitable means forthis purpose may be used. As herein shown, the part 9 is provided withan end piece 11 small enough to be inserted in the tube. The holdinpieces 12 are inserted in the openings in t e pieces 4 even strainsbeing and 5 and are movably connected with the end piece 11 so that theycan be spread apart as the pieces 4 and 5 are spread apart. As hereinshown, the holding pieces 12 are provided with reduced portions whichwork in slots 13 in the end piece 11. The expanding piece 8 ispreferably provided with guides or wings 14 which pass between thepieces 4 and 5 as shown in-Fig. 4 so that said pieces will be rotatedwhen the part 9 is rotated. two radiator sections together for example,

the short tube 3 is placed in position in the openings in the sectionsand the pieces 4 and 5 inserted therein as shown in Fig. 2. In thisposition the portion of the part 9 between said piecesis small so as tolet them come together a suflicient amount to permit them to be insertedin the tube. Theexpanding device 8 is now forced in between thepieces 4and 5 so as to spread them apart V and the expanding device and part 9arerotated so asto'e'xpand and flange thefends of the tube 3 and as itwere rivet them to the radiator sections so as 'toprovide a tightconnection between said sections, the parts being in their expandedposition with the connection completed as shown in Fig. 3'. After theends of the tube 3 have been properly expanded and flanged, theexpanding device 8 is removed from the pieces 4 and 5 and the toolwithdrawn from the tube. It will thus be seen that by means of thisconstruction, the radiator sections may be easilyyquickly and cheaplyconnected together by means of a simple but yet tight and secureconnection, without the use of screw threads, gaskets or bolts, and bymeans of a simple short section of a pon necting pipe or tube. Thisdevice connects the sections together without undue or undevelopedthereby pre venting injury to the parts.

In Figs. 2 and 3, I have shown beveled end faces on the two radiatorsections, but it is of course evident that this is not neces sary andthat the device may be applied to the ordinary sections without theseinclined faces and where the portion around the openings is of anyordinary form and construction.

I claim:

3. A sectionalradiator tube, connector, expander and flanger'comprisingtwo separable segment parts adapted to be inserted in the short tubebetween the radiator sections, said parts having enlarged ends connectedto the body portion by inclined faces, a controlling -part passingbetween said separable parts and to which they are movably connected, anexpanding part connected with said controlling part and adapted to beforced between, -said separable parts so as to spread them apart.

4. A sectional radiator tube, connector,

5. A sectional radiator tube, connector, expander and flanger comprisingtwo separablesegment part having enlarged ends, said separable partsprovided with grooves on their adjacent faces, a controlling deviceadapted to pass intosaid grooves comprising two parts, one larger insize than the other, the largerapart adapted when forced with laterallyprojecting guides which pro" ject beyond said grooves and between saidseparable parts, an end piece connected with said controlling device,and connecting pieces movably connected with sa'id'j nd piece andengaging said separable pays.

In testimony whereof, I atlix my Ignature in the presence of twowitnesses this 12th day of November 1912.
